SPECIFICATION forming part of Letters Patent N0. 349,235, datedSeptember 14, 1886.

Application filed November 19, 1885. Serial No. 183,323. (No model.)

To all whom it may concern.-

Be it known that I, EDWARD F. REYNOLDS, a citizen of the United Statesof America, residing at Bruce, in the county of Brookings and Territoryof Dakota, have invented certain new and useful Improvements inFanning-Mills 3 and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to lettersor figures of reference marked thereon, which form a part of thisspecification. My invention relates to fanning-mills; and it consists incertain novel constructions and combinations of parts hereinafterdescribed, and pointed out in the claims.

In the accompanying drawings, which illustrate my invention, Figure 1 isa longitudinal vertical section of a fanning-mill embodying myinvention. Fig. 2 represents detail per,

spective views of the vibrating sieve and the vertical separatordetached from each other and from the fanning-mill. Fig. 3 is atransverse sectional view of the vertical separator, and Fig. 4 is adetail view of one of the angle-arms for vibrating the sieve from theshaft of the rotary fan.

A represents a fanning-mill of ordinary construction, which is providedat its top with a hopper, a, into whichv the grain to be cleaned is fed,said hopper having an opening which is located above the front end ofthe vibrating separator B.

0 represents the fan, which is located within a suitable casing, and theshaft upon which said fan is mounted is rectangular in cross-section.Upon these rectangular portions of the shaft the front end of thepivoted bent arm D rests, so that when said shaft is rotated the frontend of this bent arm will oscillate.

I) I) represent supporting-straps, which are pivotally attached to thesides of the fanningmill at their upper ends, and their lower ends arepivotally connected to the sides of the separator B, and at the lowerforward ends of the separator is located at each side an outwardly-projecting pin, 1), with which the bifurcated end of one of thebent arms 1) engages, so that when the fan is rotated the separator Bwill be vibrated. The separator B is provided in its upper portion withone or more sieves, 0, upon which the uncleaned grain is fed from thehopper. The blast from the fan will blow the chaff away from the grainand out of the opening at the rear upper portion of the mill. The bottomof the separator B inclines forwardly, as shown, and is provided at itslower end with downwardly-projecting pins d, which engage withperforations in the upper end walls of the vertical separator E. Thevertical separator E is made up of two sections, E and E, which aredetachably connected to each other, and the upper ends of the rearvertical side pieces are provided with pen forations d, into which thepins d, attached to the separator B, enter, and the lower ends of theend pieces are rounded, as shown at f, and rest upon longitudinal barsf, attached to the frame. The frame of the vertical separator E is heldin position at its lower end upon the horizontal bars f by means ofhooks g, which are attached to the frame and enter eyes in the lowerrear corners of the separator-casing, so that the vertical separator canhave a rocking motion upon its supporting-bars f. Each of the endpieces, E E and E E, have rigidly secured thereto a series of inclinedboards, F, and these boards are provided with inclined sieves F, whichform a central serpentine passage in connection with said boards. Theseboards are so located between the vertical side walls as to'leave apassage between said walls and the ends of the boards. The board h extends outwardly beyond the front side of the vertical separator andprojects over the rear end of a drawer or tray, H, and the lower end ofthe vertical separator is provided with boards 2' and '5, the board ibeing located at about the center of the separator, while the rearboard, i, extends from its bottom to the end of the lower inclinedboard, as shown, and beneath the same is located an inclined board, 70,onto which the cockle or other foreign seeds fall. It will be noticedthat the vertical separator is provided with three serpentinepassage-ways, J, J, and J.

' The operation of my machine is as follows: The grain to be separatedis placed in the hopper and the fan rotated in the usual manner. Thegrain and chaff are fed upon the sieve c, and by vibrating the shoe andcausing the blast to'pass through from the under side of said sieve thechaff and lighter impurities are separated from the grain. Thepartiallycleaned grain then falls upon the bottom board of theseparator, and is fed into the center passage-way, J, of the verticalseparator, and in its downward course comes in contact with the inclinedsieves, which cause the foreign seedssuch as mustard, coekle, and othersimilar seeds-to be separated from the good grain, the good graincontinuing downwardly until it reaches the bottom of the verticalseparator, where it is fed upon the board K in a cleaned condition,while the impurities are fed into the receptacle H, and into areeeptaelewhieh may be placed under the fanning-mill in rear of saidboard K, and under the opening between said board and the rear wall ofthe vertical separator. It will be noticed that the horizontal andvertical separators are both vibrated in unison by the pivoted arms,each resting upon the shaft of the fan.

It desirable, the vertical separator herein described may be usedimlependently of the separator, and the object in making said verticalsieve in two separable parts is that areess can be readily had, whendesired, to the iuterior for cleaning the sieves.

I elaim- 1. The combination, in a fanning-mill. of a fan, the horizontalvibrating separator, and a vertical separator having a serpentinepassage-way consisting of inclined boards and in clined sieves,substantially as shown, and for the purpose set forth.

2. The combination, in a fanning-mill, of a supply-hopper, a blast-fan,the horizontal vibrating separator, a vertical separator provided with aseries of inclined boards and sieves forming a serpentinepassage-way,and devices for connecting the horizontal and vertical separators,whereby the movement of the former is imparted to the latter,substantially as described.

3. In a ianniug-mill, the combination of the main frame, the fan 0,fan-casing, horizontal separator B, connecting-arms D, and fan-shaft forvibrating the same with the vertical separator pivotally supported onthe main frame and means for connecting it at its upper end to thehorizontal separator, substantially as shown, and for the purpose setforth.

In testimony whereof I affix my signature in presence of two witnesses.

EDWARD F. REYNOLDS.
